Its lack of anything like "class" but having provisions for "race" and a framework for various supernatural [read: alien] abilities would make a modified version of Shadowrun 2/3 work well, but there are no useful spacecraft. A model of spacecraft creation exists in the Rigger vehicle creation rules, but a lot of work would be required. My point, however, being that if it's a question of what tyles of mechanics work well for science fiction, Shadowrun's flexible enough to provide such a framework, although it'd be too much of a pain in the ass for anyone I know to bother with.

Quote from: Dr Rotwang!;229297How the monkey was a zat gonna work?  Finally I suggested that it be a transformation power; first hit transforms you into a stunned dude, the second transforms you into a dead dude, and the third one transforms you into a ...no, no, no, we said, backed up...and dropped it.

A fine example. We've seen people take two zat blasts and still not be knocked unconscious, and even cases in which the third shot kills and doesn't vaporize. For Shadowrun, you'd set the Power of the weapon high enough that people with even high bodies are just barely able to reach it, but it's statistically possible, and make the damage Stun. [And 1/2 Impact armor.] Say 15D Stun: one shot runs you all the way up to 10 points of Mental Damage, the second almost certainly then fills your Physical Damage. The third shot...well, Shadowrun doesn't have rules for vaporizing things, either, but I'd think it'd be an Object Resistance roll and if the opposed roll doesn't get a certain number of successes, it disappears.
